摘    要:对不同细集料粒径组成的沥青砂浆进行单轴压缩蠕变试验,用Burgers模型拟合蠕变试验结果,并通过灰熵法分析了细集料粒径对黏弹性参数的影响程度,以研究沥青砂浆的黏弹性特性。研究结果表明:1.18~2.36 mm档集料对黏弹性参数E1、E2、η2均产生显著的影响;小于0.075 mm档集料对4个黏弹性参数的影响程度都居于其次;2.36~4.75 mm档集料对参数η1的影响程度显著。

关 键 词:道路工程  沥青砂浆  细集料  蠕变试验  Burgers模型  影响程度  灰熵法

Abstract:Uni-axial compression creep test is carried out on asphalt mortar of different fine aggregate compositions,and the results of creep test are fitted by Burgers mode.Then the influence degree of fine aggregate particle size on viscoelastic parameters is analyzed by the gray entropy method,in order to make a preliminary study of the viscoelastic property of asphalt mortar.The results show that: the aggregates ranging from 1.18mm to 2.36mm exert significant influence on viscoelastic parameters E1,E2 andη2;the influence of aggregates smaller than 0.075mm on four viscoelastic parameters takes the second place;the aggregate ranging from 2.36mm to 4.75mm exerts significant influence on viscoelastic parametersη1.
Keywords:road engineering  asphalt mortar  fine aggregate  creep test  Burgers model  influence degree  gray entropy method
